TILE FOR WALL STRUCTURES.

To all whom it may concern:

Be it known that I, FRANK DooHnAL, a citizen of the United States, residing in the city of St. Louis, State of Missourl, have invented certain new and useful Improvements in a Tile for Wall Structures, the same forming a continuation 1n part'of my application for United States Letters Patent, filed April 17th, 1916, Ser1al No. 91,530, and of which the follow-1.1g 1s a specification.

My present invention relates to an endless and interlocking tile wall structure as a whole, and more particularly to a t1le from which the wall may be formed.

The object of my invention is to provide a specially constructed hollow tile which can be easily made and whlch w1ll be strong,

durable andeasily placed into a wall structure either of a reinforced or a non-reinforced type.

- A further object of the invention is to so construct the hollow tile that when the same is filled with a cementitious material,

the inner and outer wall thereof will befirmly united, also thatthe adjacent tile in the contiguous course will be anchored or united together end for end in an endless solid wall.

A further object of the inventlon is to provide the upper face of the central cross wall and the end walls upon one side of the longitudinal center of the tile with a reinforcing rod receiving recess.

With the above and other objects in view my invention consists in. the novel construction of a. tile hereinafter described, illus partly as a hollow wall and partly as a solid wall.

Fig. 2 is a perspective view of a tile constructed in accordance with my invention.

Fig. 3. is a detail partly in vertical sec- Specification of Letters Patent.

Application filed April 26, 1917. Serial No. 164,599.

tion and partly in full lines of a pair of tile provided with a horizontal'and a vertical reinforcing rod embedded in cement.

Fig. 4 is a plan view of a circular wall construction formed of tile made in accordance with my invention. A portion of this wall being shown as a hollow Wall and the remainder as a solid wall.

Fig. 5 is a modified form of tile employing only one rib on each side of the center crosswall instead of two, as shown in Fig. 2, and which rib on each side of the center cross wall in this modified form carries out the same function as two ribs formed on either side of the center cross-wall.

The walls as shown in Figs. 1 and 3 of the drawing are formed by my improved type of tile including the cementitious filling and the reinforcing rods. The tile are arranged in the usual contiguous courses to break joints with the tile of the adjacent courses.

In carrying out the aim of my invention I employ a specially constructed tile and for this purpose it is constructed as follows:

The walls'l and 1 are connected by means of a centrally arranged and transversely disposed cross-wall 2. The cross-wall 2 is provided on each face with a pair of suitably spaced vertically disposed and longitudinally extending ribs 3 and 3. These ribs, it will be observed, are preferably arranged in opposed pairs. The side walls 1 and 1 terminate at each end in the inwardly prorespectively, which walls 4 and l in turn terminate in longitudinally disposed ribs 5 and 5 respectively, which ribs are preferably in alinement with the ribs 3 and 3? respectively, as clearly shown in Fig. 2-. A passage 6 is formed between the free ends of each pair of ribs 3 and 5 and 3' and 5 which passages communicate on one side with the side pockets 7 and uponthe opposite side with the centrally disposed pockets 8 formed between the inner faces ofthe ribs 3 and 3 and the ribs 5 and 5. These pockets are formed on each side of the central cross-wall 2, as clearly shownin Fig. 2. The pockets 8 it will be observed have the open ends 9. The ribs, pockets and passages are all preferably vertically disposed, as lllustrated.

The center cross-wall 2 and the end walls 4 are each provided with a concaved remforcing rod receiving recess lt). It will be observed that the upper end of each web 3' and 5 as well as the cross wall 2 and the upper end of each wall 4' form the bases of the recesses 10. The object of these recesses, which are formed in the upper face of the cross-walls of the tile and to one side only of the longitudinal center thereof, -1s to provide a channel and supportmg means for a horizontal reinforcing element 11. The inner wall of the recess formed in the upper face of the central cross wall 2 acts as a stop for the reinforcing rod 11 thereby preventing extreme lateral move ment of the reinforcing rod 11 at the middle portion of each tile from any cause or undue strain applied to the reinforcing rod while constructing a wall.

Having reinforcin element 11 positloned upon one side of t e longitudinal. center, and upon the upper face of the tile, permits the reinforcing rods 12 to be positioned along the longitudinal center line of the tile instead of to one side thereof, thus adding greater strength 'to the wall agamst wind pressure, while the ofiset horizontal reinforcing element 11 binds the outer half of the wall together. This reinforcing element 11 is preferably positioned in this 0E- set position to overcome defects caused by contraction and expansion of the outer half of the wall.

' t od, that the, side walls 1 and 1 are firml In building a circular wall structure, as shown in Fig. 4, for use, for instance, as silo or stack purposes the inside wall, it will be observed, 1s concaved at 13 and the outer wall is convexed as at 14. The end walls 4 and 4' are converging as clearly shown.

When the tile is used in stack, silo, or

similar circular wall construction, it will be observed that I emplo a split circular reinforcingarod 11 in com ination with one or more vertical reinforcing rods 12 placed upwardly throirjgh reach or each alternate tile.

By referring to "that portion of the wall which is shown as solid due to the use of the cementitious filling 15, it will be underanchored orunited by means of the cementitious filling deposited in the pockets-7 and 8 and the assages 6 of the tile and that due to this fil mg it is impossible for any part or parts of the side walls to fall out should they break for any reason after the filling has set in the pockets and passages, which breaking may be due to any of many causes such for instance as expansion or contraction of the materials used in the wall structure. It will be further observed that the ribs 3 and 8 ortheir equivalents on either side of the center cross-wall 2 firmly unite the cementitious filling on each side of the ribs formed at ea iterates center cross-wall 2 by adhering to the face of the wall'2 and to the faces of the ribs 3 and 3' or their equivalent.

I have shown in Fig. 5 of the drawing a slight modification in the formation of the .that shown if found necessary or desired.

One rib, in this instance, is formed on each side of the center cross-wall 2 instead of two suitabl spaced ribs 3 and 3, as shown in Fig. 2 o the drawing.

It is obvious from the foregoing description and the illustrations, that I have formed a tile which when laid to form a titious filling.

I am aware that minor slight changes maybe made in the specific form or location of the several ribs employed in .m improved form of tile, hence, I reserve t e right to make any such changes or modifications in the formation or location of these ribs as may fairly fall within the scope of the a pended claims without departlng from t e spirit or scope of my invention.

What I claim is:

1. A tile comprising an inner and outer wall, a central cross-wall uniting said inner and outer walls, a pair of suitabl spaced ribs formed at each side of sai central cross-wall, a short end wall formed at each end of said inner and outer walls and terminating in an inwardly projecting rib.

2. A tile comprising an inner and outer wall, a central cross-wall uniting said inner and outer walls, a air of suitably spaced cl: side of said central cross-wall, a short end wall formed at each end of said inner and outer walls and ter- .minating in an inwardly projecting rib,

end of said inner and outer walls andter mmatlng in an inwardly projecting rib, said,

ribs and walls adapted to form a plurality of pockets on each side of said central crossl, the pockets on each side of said central cross-wall adapted to communicate with each other.

central 4. A tile comprising an inner and outer wall, a central cross-wall uniting said inner and outer walls, a pair of suitably spaced ribs formed on each side of said central cross-wall, a short end wall formed at each end of said inner and outer walls and terminating 1n an inwardly projecting rib, said ribs and Walls adapted to form a central pocket having an open end on each side of said central-cross-wall, and a pair of side pockets formed on each side of said central cross-wall adapted to communicate with thereof, a pair ofsuitably spaced ribs on each side of said central cross Wall, a short end wall formed at each end of said inner and outer. Wall and terminating in an inwardly projecting rib.

6. A tile comprising an inner and outer wall, a central cross wall uniting said inner and outer wall, means formed on the upper face of said central cross wall adapted to act as a stop for a horizontally disposed reinforcing rod and prevent inward lateral movement thereof at the middle portion of the tile, a pair of suitably spaced ribs formed on each side of said central cross wall, a short end wall formed at each end of saidinner and outer Wall and terminating in an inwardly projecting rib.

In testimony whereof, I have hereunto signed my name to the specification.
